Seirin High vs Hakuryō High was the fifth round of the Interhigh preliminary.
Having already played a match the same day, Seirin's stamina was pressured. Despite this, the team was fired up again by Hyūga's clutch speech. Kagami managed to tip in the balance-changing basket and Seirin won by a 2-point margin.[1]

Trivia

While parts of the match were seen in the manga, it was skipped entirely in the anime.
